Compatibility matrix: cleaning and disinfecting agents compared with PC/PMMA/coatings
This overview explains which cleaning and disinfection agents are compatible with PC, PMMA and coatings, and what to consider during use.
Introduction
The selection of the right cleaning and disinfecting agent is crucial to ensure the service life of materials such as polycarbonate (PC) and polymethyl methacrylate (PMMA). A wrongly chosen cleaning agent can lead to material damage, which can cause considerable problems in industrial use. A careful analysis of material compatibility is therefore essential.
Material structure and chemical resistance of PC and PMMA
Polycarbonate and polymethyl methacrylate are transparent thermoplastics that are used in various industrial applications. While polycarbonate is known for its impact strength, PMMA is distinguished by high optical clarity. However, both materials are sensitive to aggressive chemicals.
Polycarbonate (PC)
Polycarbonate offers excellent impact strength and heat deflection resistance. Nevertheless, contact with organic solvents or strongly alkaline cleaners can cause stress cracks.
Polymethyl methacrylate (PMMA)
PMMA, often known as acrylic glass, is more scratch-sensitive than PC. Its chemical resistance is limited, particularly to acids and alcohols. Appropriate precautions must therefore be taken during cleaning.
Compatibility matrix: cleaning and disinfecting agents
The compatibility matrix supports technical buyers and production managers in selecting the right care products. The table provides an overview of which agents can be used safely.
| Cleaning agent | PC compatibility | PMMA compatibility | Application notes |
|---|---|---|---|
| Neutral cleaner | Compatible | Compatible | Short exposure time recommended |
| Alcohol-based disinfectants | Not recommended | Damages surface | Do not use |
| Ammonia-based cleaners | Limited compatibility | Not recommended | Test beforehand |
| Special plastic cleaners | Compatible (as recommended) | Compatible (as recommended) | If in doubt, test on a small area |
Application tips and notes
For efficient cleaning and disinfection without damage, the following notes should be observed:
- Always test a small area before treating the entire product.
- Use soft cloths to avoid scratch formation.
- After application, rinse with clear water to remove residues.
Conclusion
Industrial applications require precise material care. Sound knowledge of the compatibility of cleaning and disinfecting agents helps to maximise the performance and service life of PC and PMMA. When selecting products, the specific material compatibility should always be the priority.

Frequently asked questions
Which cleaning agents are suitable for polycarbonate?
Neutral cleaners and special plastic cleaners are suitable for polycarbonate. Alcohol- and ammonia-based agents should be avoided.
Why are alcohol-based agents unsuitable for PC and PMMA?
Alcohol-based agents can cause stress cracks and surface damage to PC and PMMA.
How do I test a cleaning agent for material compatibility?
First apply the agent to a small, inconspicuous spot to observe the reaction of the material.
Which care instructions should be observed for PMMA?
PMMA should be treated with mild cleaners and cleaned with soft cloths to avoid scratches.
What is the advantage of a compatibility matrix?
It provides a quick overview of suitable cleaning agents in order to avoid material damage and extend service life.
